UV Weathering Test UV-stability tested by Fraunhofer ISE Commissioned by HellermannTyton, the Fraunhofer Institute for Solar Energy Systems ISE carried out an extended UV weathering test according to IEC 61215, subsection 10.10. For this purpose, four cable ties of different materials were fastened under load to test cylinders and then exposed to UV radiation at controlled intervals inside a test chamber. Thereafter, the ties were subjected to a loop strength test performed according to section 9.5.1 of the VDE Institute‘s DIN EN 62275:2010.07. The specimens spent up to 1,600 hours in the test chamber and were exposed to a UV dose of 156.78 kWh/m2. This amount of artificial irradiation complies with the assumption that Central Europe is exposed to natural solar irradiation of 1,000 kWh/m2 per year, with about 5% of this being in the damaging UV range. The test corresponded to approximately 3 years of outdoor exposure. Since the intensity and coherence of UV irradiation in the test
chamber are not met under natural conditions, these values will be compared to the results of an on-going comparative outdoor exposure over 3 years in Freiburg, Germany and the Negev Desert in southern Israel. The graphs below depict the mean results of the cable tie loop strength test after artificial UV weathering. The natural-coloured, conventional polyamide 6.6 cable tie (width 7.7 mm) already showed significant material degradation caused by the UV radiation after 200 hours in the test chamber. The loop tensile strength of this non-UV-stabilised material sank to below half its initial value. In contrast to this, it is apparent that the Q50L-W and T80R-W, made of UV-stabilised polyamide 6.6, as well as the GL250, made of polyamide 11, show virtually no effects of UV weathering.

With its revolutionary, time-saving open head design, the Q-tie is available in a wide range of sizes.
Q-tie Cable Ties The new Q-tie cable ties are revolutionary due to their open head design. When using cable ties with a conventional head design, the tail of the strap must first be fed through the slot in the locking head. Only after a change in grip can the tie be tightened. With the new Q-ties, these two assembly steps are a thing of the past. Simply insert the ergonomically bent tail into the open side of the head and tighten the cable tie. The fastening process is complete.

Fixing Ties for Edges • EdgeClip Family Key features The fixing components of the EdgeClip product range were developed for routing and bundling of cables or pipes along edges. They are suitable for edges from 1.0 to 3.0 mm wide and 3.0 to 6.0 mm wide edges. The clip is easily applied by hand and the integrated metal clamp holds the it firmly in place. No drilling of holes is required. In combination with our the OS-Series of outside serrated cable ties or the innovative Q-Series, the EdgeClip is a dependable mounting solution. The silver-grey clamp, the heart of our EdgeClips, consists of double-tempered spring steel in accordance with DIN EN 10132-4 C75S. The spring steel gives the clamp both the necessary rigidity to provide high pull-off forces and also sufficient flexibility for various possible applications.

Due to its broad front end, the stainless steel clip can easily be pushed on.
Up to 2 solar cables of typical diameters 4.0–10.0 mm2 can be routed.
The retaining claws on both sides ensure secure fastening.
Stainless steel EdgeClip • MSC2 Key features The innovative EdgeClip is made of stainless steel and was developed for very demanding applications where use of plastics alone is no longer the preferred fastening method, for example in desert-based solar parks or applications in the immediate vicinity of salt water. The corrosion-resistant MSC2 can be easily manually pushed onto the frame of solar modules or aluminium or galvanized steel edges measuring 1.0 to 3.0 mm thick.

Technical Specifications
The retaining claws on either side provide a secure fastening on both sides of the edge. On the cable holder side, the edges are especially rounded, so that the solar cable cannot be damaged. The clip can hold 1 or 2 solar cables with typical diameters ranging from 4.0 to 10.0 mm2 lengthwise to the edge.

Cable Ties and Fixings
GalvaLok and PA66 ties after 24 hours in a saturated zinc chloride solution at +90°C.
GalvaLok Cable Ties • GalvaLok Key features The GalvaLok ties are made of high-performance polyamide 11 (PA11), which is derived from sustainable castor oil sources and is characterised by its extreme resistance to chemicals such as zinc chloride as well as UV-radiation. A special use is the bundling and fixing of solar cables on galvanized steel frames in coastal areas. Here, salt in the air in combination with water forms a solution of zinc chloride on galvanized steel frames, which can lead to extreme corrosion of conventional polyamide 6.6 (see image comparison).
Use of GalvaLok in the solar industry.

Clips and Screw Fixing Mounts Key features The focus here is on the design and application of alternative mounting solutions for solar cables. Bases made of UV-stabilised material to be used with a mounting screw is a viable option for permanent fixings, especially for smooth frames. Our Solarclip SC6.6 is ideal for mounting bases to pre-drilled rectangular profiles. The twistable HC2X7.3AH13-PV fastening clip makes it simple to attach one or two cables to solar panels along two different types of groove.
